Report of Independent Registered Public Accounting Firm


To the Board of Trustees and Shareholders of Natixis Cash
Management Trust

In planning and performing our audit of the financial statements
of Natixis Cash Management Trust - Money Market Series (the
"Fund"), a series constituting Natixis Cash Management Trust,
as of and for the year ended June 30, 2009, in accordance with
the standards of the Public Company Accounting Oversight
Board (United States), we considered the Funds internal
control over financial reporting, including controls over
safeguarding securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of
Form N-SAR, but not for the purpose of expressing an opinion
on the effectiveness of the Funds internal control over financial
reporting.  Accordingly, we do not express an opinion on the
effectiveness of the Fund's internal control over financial
reporting.

The management of the Fund is responsible for establishing
and maintaining effective internal control over financial
reporting.  In fulfilling this responsibility, estimates and
judgments by management are required to assess the
expected benefits and related costs of controls.  A funds
internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted
accounting principles.  A funds internal control over financial
reporting includes those policies and procedures that (1)
pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of
the assets of the fund; (2) provide reasonable assurance that
transactions are recorded as necessary to permit preparation
of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the
fund are being made only in accordance with authorizations of
management and trustees of the fund; and (3)  provide
reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of a funds
assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may
deteriorate.

A deficiency in internal control over financial reporting exists
when the design or operation of a control does not allow
management or employees, in the normal course of performing
their assigned functions, to prevent or detect misstatements on
a timely basis.  A material weakness is a deficiency, or a
combination of deficiencies, in internal control over financial
reporting, such that there is a reasonable possibility that a
material misstatement of the Funds annual or interim financial
statements will not be prevented or detected on a timely basis.

Our consideration of the Funds internal control over financial
reporting was for the limited purpose described in the first
paragraph and would not necessarily disclose all deficiencies in
internal control over financial reporting that might be material
weaknesses under standards established by the Public
Company Accounting Oversight Board (United States).
However, we noted no deficiencies in the Funds internal
control over financial reporting and its operation, including
controls over safeguarding securities, that we consider to be
material weaknesses as defined above as of June 30, 2009

This report is intended solely for the information and use of
management and the Board of Trustees of Natixis Cash
Management Trust and the Securities and Exchange
Commission and is not intended to be and should not be used
by anyone other than these specified parties.
